Title: Electrical signal transmitter
Inventor: JR CHARLES EDWARD ROESSLER
IPC: G01G7/04
Filed: 1959-05-04
Abstract: 916,020. Linkwork. HOWE SCALE CO. May 4, 1959, No. 15233/59. Class 80 (3). [Also in Groups XVIII and XXXVIII] Linkage for ensuring that the linear movement of the armature of an electric transducer with respect to its coil system is accurately proportional to the angular movement of a shaft 11 (e.g. of a weighing-machine), comprises a disc 40 and band 42 attached to the end of a lever 28, which is pivoted asymmetrically at 24 so that its weight keeps the band taut. The lever 28 carries the armature 8 by a rod 39 which is fastened by means of pins 37 and 35 mutually at right-angles. This fastening is seen from different directions in Figs. 4 and 5 (not shown). The armature is aligned accurately with the coil system 12 by means of screws 17 and 33 for transverse adjustment of the two units respectively; a pin 15 is also provided to adjust the separation of the bottom of the coil bracket 13 from the main bracket 10 and hence tilt the coil bracket (further details in Fig. 5, not shown). In addition, the coil system can be moved axially relative to the clamp 18. The initial attachment of the band 42 to the disc 40 is chosen so that zero electrical output corresponds to a desired angular position of the shaft. For best accuracy the disc, band and lever are all of the same axial thickness, and a median plane perpendicular to the shaft 11 and the pivot pin 24 bisects all three. In addition, the band forms a common tangent to the disc and lever which is vertical for all positions of the shaft. The disc and lever may be on opposite sides of the band. Errors due to the motion of the upper end of the rod 39 being arcuate instead of linear are small, but can be cancelled out by suitable modification of the surface of the disc 40 or lever 28, preferably the former.
